Dunlop Q5 Sportmax Tires The fifth generation Dunlop Sportmax Q5 is a purpose-built, DOT compliant track-day tire that has been in the making for over 4 years. Evolving from a blend of the highly popular Sportmax Q4 and Dunlops cutting-edge MotoAmerica spec road race tires, the Q5 utilizes the very best technologies Dunlop has to offer for a track tire that is still street legal. Having enhanced constructions, profiles, compounds and tread patterns, the Q5 is the benchmark for track-day tires. The Q5 is even more user-friendly, as dry and wet grip, tire compliance and warm-up times have all been improved. Dunlop changed the polymer, reduced the shore hardness, increased the carbon black content by utilizing Carbon R technology, added a traction resin and fine-tuned the curatives, all to greatly improve upon the already successful Q4. They also optimized the tread pattern design and position to aid in quicker warm-up times and improved wet-weather performance.
